Method Of And Apparatus For Coating A Molded Fibrous Workpiece
US Patent:
5514417, May 7, 1996
Filed:
Aug 4, 1994
Appl. No.:
8/286027
Inventors:
Kent R. Matthews - Littleton CO Eric G. Schakel - Sedalia CO Lowell K. Morton - Greenville SC James F. Young - Greenville SC
Assignee:
Schuller International, Inc. - Denver CO
International Classification:
B05D 312, B05D 118
US Classification:
427358
Abstract:
Molded fibrous workpieces of various cross sectional configurations are coated with a polymeric latex foam coating material to encapsulate fibers and dust within the exterior surfaces of the workpieces. The foam coating is applied by passing the workpieces through a coating chamber filled with the polymeric foam so that the workpieces are totally immersed in the foam coating as the workpieces pass through the chamber. Openings for introducing the workpieces into and discharging the workpieces from the chamber have a configuration complementary to the transverse configuration of the workpieces. The foam coating is introduced into the chamber both above and below the path of the workpieces through the coating chamber to assure that the coating chamber remains fully charged with the foam coating. Brushes or wiper blades spread the foam coating over the exterior surfaces of the workpieces.
